Imagine being trained to teach the PADI Public Safety Diver and/or the Advanced Public Safety Diver course by the guy who wrote their PSD courses. How cool is that? Mike Berry teaches these 1-day programs to PADI Instructors who meet all the prerequisites. Here is the catch, you also have to take Mike's PSD or Advanced PSD course making your instructor course 4-days long so you can be taught by Mike how the courses were designed to be taught. One of the most important prerequisites is "Experience." It's hard to teach others a subject you yourself know very little about. So, don't come if you lack this ingredient and you are looking for another specialty to teach!
